Do Regular White LED Lights Help Plants Grow?

Yes.

White LEDs can be used when the light is not enough. It's just that the utilization rate of light is not as high as that of dedicated growth lights for plants. Under the same power, white light consumes a lot of energy on other wavelength bands that plants cannot absorb. As for growth lights, the light emitted is basically the very spectrum in the wavelength range that plants can use. 

The same effect as plant lights can be achieved by increasing the number and power of white LEDs. But it takes groping. LED plant lights are much more expensive than white lights, so in fact, apart from the electricity bill, there may not be much difference in cost. Electricity bills are indeed a relatively large expense.

  based on my experience. The lamp is about 1 meter away from the plant. To care for a plant of about 1 square meter, a 200-watt white LED is required. If you have a lot of plants and a large site, you need to increase the number of lights. Because the light is far away, the light weakens obviously. To be even, to illuminate a wide range. When there are many plants, the power consumption will be significant. The cost is high. Pay special attention to power issues. Thinking that 1-2 LED bulbs of a few watts, or more than a dozen watts can solve the problem, that is not enough. Unless your bulb is very close to the plant. Be careful it gets hot.

The advantage of white light is that it will have a good color rendering for indoor plant landscapes, such as plant walls and plants in tanks. Meet the needs of human vision. The plant lights are red, blue and purple. Although it has a high utilization rate of plants, it looks uncomfortable and unnatural to human eyes. Therefore it is limited. It can be used for production and cultivation. Appreciation of aesthetics used to take care of plant landscapes is not acceptable. The white light well takes into account the two needs of appreciating the plant landscape and plant photosynthesis. It also has its uses. Different needs use different lights.
